摘要

Method of extending an object on the sea bed in very deep waters from a boat with a crane to compensate for swing, and device to bear the load of an object submerged suspended in a vessel.It is described a method of extending an object (14) on the sea bed in very deep waters from a vessel that has a crane on the platform to compensate for swing (12), which includes lowering the object at a distance in the sea while it is suspended on the cable of the crane (16).In an initial stage, a first section of rope fiber (4a) of a first length is connected to the object (14) through a first connector (3a) in the object before the lowering start and run freely out of the support a reel for storage (13) during the descent.Subsequently, the first section of rope is connected to the object by means of a second connector (3b) located at the upper end of the first section of rope (4a), the second connector being supported by a support mechanism (1) on the platform of the vessel (8),Followed by unloading of the cable of the crane (16) and disconnecting the object and lifting it to the said first length for connection in the second connector (3b) on the platform of the vessel and assuming the load to the object.Then, the object (14) is lowered a second length in water by crane while a second section of rope (4b) connected in the second connector runs freely to the outside of a storage reel (13) until a third connector (3C) located at the upper end of the social The NDA rope support the load of the object on the support mechanism (1),By the hook of the crane can be released and taken up to the reconnection in the third connector (3C) for further extension, and any additional extension by addition to the sequence of strings, thereby allowing the object (14) to reach a depth of 3000 meters, or Even more.
